Methinks, purge meter decay rate is only the tip of the iceberg.
The entire Purge system needs an overhaul, as do many other systems. Here was another discussion: Decay, purges, and inactive players.
Instead of restating what is being repeated already. I would address:
I believe the game has reached a point, after all the DLC packs, that requires the “sandbox” be cleaned and polished before adding more. As I said above, many systems need to be refined to allow for further content.
However, something to do (like fight purges) while Funcom cleans the box would be appreciated… it’s either that, or browse other games while refreshing and waiting.
